BOTTLE paprika DEVICE I Thorvald M i 31; masses amiss-16L 18 Claims. (CL 225-9 j v v I Fig. 7 is aifragmnwryiscflohal elvationl on ."'his invention relates to improvementsin devices for placing caps on bottles, and particularly for use in connection with-the placing of paper caps-into seats formed inthe' necks of bottles,

such as are commonly used formilk.

Some-objects of this invention are to provide :abottle capping device otlthis kind of improved and simplified construction which is positive and acc "rate in its operation; also to provide a capping device of this kind which is so constructed that it can-be readily taken apart for cleaning or other purposes; also to provide a bottlecapr pingdevice Which-is so constructed that even after severe use and wearing of the parts,it will still functionwith accuracy; also to provide a bottle capping device in which a single holding or locking member supports all of. themovable parts in correctrelation to the housing of the .capper, and which when moved into released position permits the xnovable parts to be removed ,from the housing ;and also to provide a capping device with a part which can bevadjusted to compensate for wear of the deviceto insure accurate operation of. the capping devicffora long period of time. a g 1 a Other objects of the invention are to construct a bottle capping device in which no springs are used to produce tension or compression for assistingthe action of moving parts so as to there-4 by'provide a device which requires much less effort to operate than such devices having springs ,therein, and whereby the invention can besue- ,ce'ssfully used for capping paper bottles without damage thereto; also to'construct a cappingdevice which can be used either for capping glass bottles or paper bottles as desired; also tojprovide an adapter for use with the improvedfcapper to enable the device to be quickly "changed for. use with either glass or paper bottles,for which will permit the capper to be used with bottles having necks or mouths of slightly dili'erent diameters or sizes; and also to improve bottle capping devices of thiskind in other rejspects hereinafter specified;
